36 Pulse (Leguminbsce)* [NO. 7 



The plant is violently poisonous to the touch, causing 

 in most persons a painful eruption : some are poisoned by 

 it without touching it, probably by means of the drifting 

 pollen of its flowers. A recommended application is 

 sugar of lead applied, after the use of saline cathartics, or 

 a thick paste of bi-carbonate of soda rubbed into the skin 

 as soon as the eruption appears. It is also claimed that 

 relief and, if used promptly, frequent cure follow the use 

 of apis mellifica or of belladonna, taken in homoeopathic 

 doses. There are wellnigh as many recommended anti- 

 dotes as there are for the bites of rattlesnakes ; and what 

 will help in some cases will not in others.
